I was accually going to put it up for storge when the snow hits (month or two if luckey)... I only have my temps, and can only drive it after bugging the living crap out of my mom for the previous week. I'm exagerating, but the point is that it wont get driven more then 300 miles (mabey closer to half of that) before I change the oil again (spring of 06)

After that I'll have my lisance, and will be driving alot, but for now I'm stuck putting my hours on the paper... I allready have 35 out of a required 30......
Anyways would running it for just a total of 500 miles on this non diesel oil hurt anything? and If it would, could I just drain the old out, and put in some diesel rated oil (same filter)?

thanks alot
